2 Claims.

The present invention relates to cotton gin ribs and has for its principal object to provide a rib construction which permits the free escape of the fibres, lint and trash from the upper end of the rib to prevent choking or clogging of the grate thereby eliminating the danger of fire.

A further object is to provide a rib construction which is eificient and reliable in use and which does not require any changes or alterations in the construction of the grate or other parts of the machine now in use.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed reference being had to the accompanying drawing forming part hereof, wherein like numerals refer to like parts throughout and in which:

Figure 1' is a fragmentary sectional view through a gin machine showing the rib mounted in position thereon.

Figure 2 is an edge elevational view of the rib.

Figures 3, 4 and 5 are transverse sectional views through the ribs taken substantially on the lines 3-3, 44 and 55 respectively of Figure 1.

Referring now to the drawing in detail, wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention, the numeral 5 designates generally the hopper of the gin machine in which upper and lower grate rails 6 and l' are positioned and between which the saws (not shown) are operatively mounted in a manner well known in the art.

The gin rib is designated generally by the numeral B and is of the usual curved formation and includes a web portion 9 having oppositely extending flanges I!) on the front edge thereof.

The upper end of the rib is formed with an attaching plate ll having an opening I2 therein for suitably securing the plate to the rail 6. The lower end of the rib likewise is formed with an enlarged head or plate I3 having openings l4 therein for securing to the lower rail 1.

The flanges l0 terminate above the lower plate l3, as more clearly illustrated in Figure 4 of the drawing and the upper edge of the flanges overlie the upper plate II and are spaced outwardly therefrom as more clearly illustrated in Figures 1 and 5.

Extending inwardly from the upper end of the rib and on opposite sides of the web 8, are vertically positioned grooves l6 which cause a material reduction in the thickness of the web as shown at I! in Figure 5.

It will be apparent from the foregoing that by reason of this construction channels are formed on each side of the web 8 extending from the upper end of the rib to a point below the upper attaching plate Ii so that lint, trash, etc., are enabled to pass downwardly between the flanges I 0 and the plate and thus prevent clogging of such material at this point of the gin. The grooves l6 thus serve to remove the lint, trash, etc., from the hopper which ordinarily are thrown against the upper rail 6 by the action of the saw which results in a clogging at the upper end of the rib, thereby forcing the saws against the rib and frequently produce sparks resulting inflres.

The present invention eliminates this objectional feature and removes the fire hazard which is generally caused in the manner above explained.

Having thus described my invention, what I claim is:

1. A gin rib including a web and laterally extending flanges and having an attaching plate at its upper end, the upper ends of the flanges terminating in spaced overlapping relation with respect to said plate and grooves in the web of the rib communicating with the upper edge thereof and extending longitudinally of the web and positioned between the flanges and the plate to provide a passageway for trash thrown against the upper end of the rib.

2. A gin rib of the class described embodying a web having flanges extending oppositely from one side thereof, and an attaching plate at the upper end of the rib on the edge of the web opposite from said flanges, said plate and flanges being spaced from each other in overlapping relation and said web being of a reduced thickness at the portion thereof extending between the flanges and the plate to provide passages at each side of the rib for the removal 'of trash thrown against the upper end of the rib.
